Modify luminance calculation and extract related functions into single files (#24586)
Close #24508
Main changes:
As discussed in the issue
1. Change luminance calculation function to use [Relative
Luminance](https://www.w3.org/WAI/GL/wiki/Relative_luminance)
2. Move the luminance related functions into color.go/color.js
3. Add tests for both the files (Not sure if test cases are too many
now)
Before (tests included by `UseLightTextOnBackground` are labels started
with `##`):
